If your device freezes or hangs, you may need to close apps or turn off the device and turn it on again. If your device is frozen and unresponsive, press and hold the Power button and the Volume button down simultaneously for more than 7 seconds to restart it. 

If after restarting the device you still find your device freezes sometimes or is sometimes unresponsive, there are some actions you can try to help correct this symptom:

1.   Use the Galaxy S7 SMART Manager app to help optimize the device and check for “Malware” . (SMART Manager

     may not be available depending on the region or service provider)

2.   Create memory space

3.   Check for software updates for your device

4.   Check your device in “Safe mode”

5.   Perform a factory data reset of the device.  Before performing the factory data reset, remember  to make backup copies of all important data stored in the device. (Samsung shall not be responsible for any data loss.)

 If the problem is still not resolved, contact a Samsung Service Centre.
